Just from looking at the script for two, I came up with this

Code:
WinGet, wowid, List, World of Warcraft

~+::
KeyWait 2
IfWinActive, World of Warcraft
{
  ControlSend,, +, ahk_id %wowid1%
  ControlSend,, +, ahk_id %wowid2%
  ControlSend,, +, ahk_id %wowid3%
  ControlSend,, +, ahk_id %wowid4%
  Return
}
Replace"+" with the button you want it too use. Please post if it works.
